Design of medical wireless location network based on Zigbee protocol
Haifeng Li, Jingtao Zhen, Yan Zhang, Chen Lei · 2007
A medical wireless location network based on Zigbee/IEEE802.15.4 is issued. The blood pressure values and location information of inpatients could be obtained and handled in time via the wireless network. The kernel chip of the system hardware is CC2430/2431. To calculate the position of mobile sensor nodes, the Location Engine of CC2431 implements a distributed computation algorithm that uses received signal strength indicator (RSSI) values from known reference nodes. This network is a typical location application of Zigbee network.
